Considering the face value of this bill, the detail on the back is
really amazing.
The center reads:

"This note is exchangeable for United States Notes by the assistant
Treasurers and designated Depositaries of the United States in sums
not less than Three Dollars. Receivable in payment of all the
United States less than Five Dollars, except customs." The
line along the center bottom of the note says: "National Bank Note
Company New York."
